Common Questions
Q: What's the difference between 3 mil and standard poly bags?
A: Standard poly bags are typically 1-2 mil. At 3 mil, these bags are noticeably thicker and more puncture-resistant — ideal for sharp parts, metal hardware, or heavier items that would poke through thinner bags.
Q: Can I use these for food packaging?
A: Yes! These bags are made from 100% virgin LDPE that's FDA food-contact compliant. They work great for nuts, candy, dried goods, or baked items that need extra protection.
Q: How do I seal these bags?
A: Flat poly bags can be heat sealed with an impulse sealer, folded and taped, or closed with twist ties. For permanent seals, heat sealing gives the cleanest, most professional look.
